NFT Marketplace on the Cardano Blockchain. Powered by Plutus Smart Contracts

Martify

NFT Marketplace on the Cardano Blockchain. Powered by Plutus Smart Contracts A simple contract that allows sales of NFTs. The seller (owner of an NFT) constructs the contract with parameters unique to the sale and locks the NFT there. A buyer can then unlock the NFT by submitting a transaction verifying the several requirements defined in the validator.

Test with cardano-cli

Put NFT for sale

• Install and run a cardano-node on the testnet, you'll now have a node.socket file. Put the path to this file in the env variable CARDANO_NODE_SOCKET_PATH
• Clone this repo https://github.com/nateshmbhat/cardano-nft-minter. It's an easy way to mint an NFT, so you can test and put it for sale
• Execute the bash script and mint an NFT, selecting testnet
• run testnet=testnet-magic 1097911063
• run cd tokens/TokenName after you minted the NFT
• run cardano-cli query utxo --address $(cat payment.addr) --$testnet
• Note down the txhash and txid containing the NFT you minted
• run cardano-cli address key-hash --payment-verification-key-file payment.vkey and copy the output
• Go into the Martify repo after you built it using cabal build
• run cabal run market-plutus
• copy the resulting market.plutus file in the folder where you minted the NFT
• run cabal run datum-json price sellerAddr tokenName policyId where sellerAddr is the output you copied previously
• copy the resulting file in the folder where you minted the NFT
• go back to the folder where you minted the NFT
• run cardano-cli address build --payment-script-file market.plutus --$testnet >> script.addr
• run cardano-cli transaction hash-script-data --script-data-file datum-policyId-tokenname.json >> dhash
• run

cardano-cli transaction build \
    --alonzo-era \
    --$testnet \
    --tx-in txhash#txid \
    --tx-out "$(cat script.addr) + 1724100 lovelace + 1 $(cat policy/policyID).tokenname" \
    --tx-out-datum-hash $(cat dhash) \
    --change-address $(cat payment.addr) \
    --protocol-params-file protocol.json \
    --out-file tx.02 

• run

cardano-cli transaction sign \
    --tx-body-file tx.02 \
    --signing-key-file payment.skey \
    --$testnet \
    --out-file tx-2.02 

• run cardano-cli transaction submit --tx-file tx-2.02 --$testnet

Cancel sale (adapt for other endpoints buy and update price)

• run cardano-cli query utxo --address $(cat script.addr) --$testnet
• Get the txhash and txid of your NFT for sale. We'll call those txhashNFT and txidNFT
• run cardano-cli query utxo --address $(cat payment.addr) --$testnet
• Get the txhash and txid of some ada at your wallet. We'll call those txhashADA and txidADA
• Go into martify repo folder and copy over the close.json file from there
• run

cardano-cli transaction build \
    --alonzo-era \
    --$testnet \
    --tx-in txhashADA#txidADA \
    --tx-in txhashNFT#txidNFT \
    --tx-in-script-file market.plutus \
    --tx-in-datum-file datum-policyid-tokenname.json \
    --tx-in-redeemer-file close.json \
    --required-signer payment.skey \
    --tx-in-collateral txhashADA#txidADA \
    --tx-out "$(cat payment.addr) + 1724100 lovelace + 1 policyid.tokenname" \
    --change-address $(cat payment.addr) \
    --protocol-params-file protocol.json \
    --out-file unlock-body.02

• run

cardano-cli transaction sign \
    --tx-body-file unlock-body.02 \
    --signing-key-file payment.skey \
    --$testnet \
    --out-file unlock.02

• run cardano-cli transaction submit --tx-file unlock.02 --$testnet
• If everything went fine, you should see your asset in your wallet
